OPA2835 VFB Amplifier

Texas Instruments' dual, ultra-low power, rail to rail out, negative rail in, VFB amplifier

Texas Instruments OPA2835 VFB Amplifier Fabricated using the industry-leading BiCom-3x (SiGe complimentary bipolar) process, Texas Instruments' OPA835 and OPA2835 are single and dual ultra-low power, rail-to-rail output, negative rail input, voltage-feedback operational amplifiers designed to operate over a power supply range of 2.5 V to 5.5 V Single Supply and ±1.25 V to ±2.75 V dual supply. Consuming only 250 µA per channel and a unity gain bandwidth of 56 MHz, these amplifiers set an industry leading power-to-performance ratio for rail-to-rail amplifiers. For battery powered portable applications where power is of key importance, the OPA835's and OPA2835's low power consumption and high frequency performance offers designers performance versus power not attainable in other devices. OPA2835 Datasheet

OPA2835IDGSEVM 296-29832-ND The OPA2835DGS is designed to quickly demonstrate the functionality and versatility of the amplifier(s). The EVM is ready to connect to power, signal source, and test instruments through the use of on-board connectors. The default amplifier configuration is non-inverting gain of 2 configuration and split supply. It can be easily configured for other gains, and single supply operation. xOPA2835IDGSEVMxx User's Guide
